    Serial port overruns are not something to be too concerned about.
    They can happen if the machine is slow at high data rates,
    under heavy load, or has a device driver that blocks
    interrupt handling for a bit too long (e.g. a slow CD
    drive access locks the machine for a couple of seconds).
    They don't normally indicate a hardware fault. But can appear seemingly at random.
